Which is not a good reason to perform step 1 in the solution below? equation: 4x=88 solution: step one: 4x/4=88/4 x=22. answer choices- a. dividing is the inverse of multiplying. b. divide by 4,because 4 is a factor of 88. c. divding by 4x by 4 isolates x on one side of the equation. d. dividing both sides by 4 keeps the equation balanced.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
